There are usually quite a few people on the Sennen Cove from November to March.
From November to April the water at Sennen Cove is too cold to swim in.
The whole year Sennen Cove has rainy season. This is something to keep in mind when planning your trip since it is quite possible that you may be unable to sunbathe.
